PC platformers with mouse aim - more complex/deep Thread

Hi.
I know similar to my description games like Abuse, or simple shotgun fun fun, or a bit different gunpoint - but what I have an itch for is a game that would have more coplex weapon systems, something like granade launchers included with aiming needing gravity consideration and bouncing - that'll be awesome!
One more game comes to mind - Worms haha! Weapons, side aiming, bouncing - all awesome, but not much of a platformer where you progress deeper into levels, which I want here.

so I'm looking for a game with shooting that would have:
-side view (unless something fits perfectly my description an has other view)
-mouse aiming
-weapon selection
-physics involved (trajectories/bouncing/etc)
-maybe not just pure fast paced fighting shooting, but some thinking/strategy needed, too?
-maybe some more combat depth, like using armors/shields/powerups/special items/ MAYBE EVEN SOME RPG ELEMENTS? for character grow in abilities etc

Ok, so it doesn't need all that, last 2 wishes are optional (would be great thought) - I havent played Abuse for a very long time but it seem to fit my description/wish the best from game I played.
Also, Shothun FunFun really is fun to play and beat own high scores, but its very fast paced and chaotic, plus very simple.
Gunpoint isn't really a shooter ant there's little of it in the game, but aiming the jump and strategic part of it is what I am after..
I have Windows 7, if it matters.

Doesn't have to be indie game, just fitting the above.

So that's it, thanks for reading and if you have any suggestions, recommendations - That'll be great.

For those who do not know Abuse game:

Gigantic Army is pretty neat: Indiedb.com
There is some more complex ones I've read about/watched videos but I can't think of them at the moment.

Thats looking very neat, thank you. Pretty intense combat for sure, but customization looks interesting. If you remember the other ones, do tell.
